Help time again


Hi all
Can anyone solve this wee problem im having
On this windowblind im making - you can see when i skin the top horizontal taskbar it overlaps
wheras the bottom bit also pictured is fine

Im using an animated start button if that makes a difference
In the preview it looks fine - also if i expand the top taskbar to two levels it works perfectly
Any ideas?
